The bug
Using the minecraft:summoned_entity trigger in an advancement doesn't account for a bunch of entities a player can create directly via placing of an item:
minecraft:armor_standminecraft:paintingminecraft:minecartminecraft:boatminecraft:leadminecraft:fireworks/minecraft:fireworks_rocket
(also, it won't work for spawn_eggs, but this might be different issue).
How to reproduce
Download the attached data pack
and place it in the
datapacksdirectory of your world folderOpen the world

→ ❌ The advancement is not madePlace two snow blocks and a pumpkin on top of each other to spawn a snow golem

Confirmed for 1.13.2-pre2. Please keep the ticket updated.
